From 953c7d025d97916e56fd6f1bd347e1c19fd7d5f5 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 27 Dec 2011 17:20:10 +0000 Subject: mfd: Still check other interrupts if we get a wm831x touchscreen IRQ It is possible that we will see another interrupt triggering at the same time as the touchscreen interrupts so it's still worth checking other possible sources. Almost all of the win from the fast path comes from only needing to read the primary register and saving the I/O costs.
